出雲ファームのこめたまご are eggs delivered from a farm in Tokuji, Yamaguchi Prefecture, and the shop describes them as eggs from hens raised on rice. They are sent in 5kg and 10kg quantities, close to commercial volume, so you should decide “how many eggs is that?” and “can we use them up before the best-before date?” before choosing. Based on the 出雲ファーム 公式楽天市場店 (the official Rakuten Ichiba store) product page and Rakuten customer reviews, this article organizes five points: the number of eggs, storage and shelf life, ingredient labeling, suitability as a gift, and reviews.
*The Amazon link goes to the same store’s item in different specifications (on Amazon, 5 kg and 10 kg are sold on separate M-size and L-size pages, and the link goes to the 5 kg L-size page; there is no LL size. Rakuten Ichiba lets you choose 5 kg or 10 kg in M, L or LL size). The amount and contents in this article are based on the Rakuten Ichiba item. Please check the details on the Amazon product page before purchasing.

Suitable as a Gift?
On the product page we could not confirm support for noshi (gift wrapping label), wrapping or message cards. We also found no mention of name printing or types of noshi inscription. If you are considering it as a gift, checking the following points with the seller before buying makes a mix-up less likely.
- Whether they support noshi and wrapping (not stated on the product page)
- Whether you can specify a delivery date and time the recipient can receive, since it ships by Yu-Pack
- Whether the recipient’s refrigerator has room for the weight you choose (5kg or 10kg) of eggs
Among the reviews we read, 2 of the first 60 in Rakuten’s default order said they sent the eggs to relatives (one uses them as a gift, and one sends them to relatives every month) (trends within what we read, which may not reflect the product’s current condition.
